Section 3: Operation
Bright
Increases or decreases the black level in the image. Use L
level of brightness. For best results, start high and decrease so that dark areas do not become fully black (i.e.,
"crushed"). Conversely, overly high brightness changes black to dark gray, causing washed-out images.
Gamma
Determines how gray shades are displayed between minimum input (black) and maximum input (white) for a
given amount of signal. The proper setting helps maintain optimized blacks and whites while ensuring a
smooth transition for the "in-between" values utilized in grays. Unlike brightness and contrast controls, the
overall tone of an image can be lightened or darkened without changing the two extremes and your images will
be more vibrant yet with good detail in dark areas when using the Gamma control.
The nominal setting for Gamma Correction of 0 is correct for most signals and conditions. If excess ambient
light washes out the image and it becomes difficult or impossible to see details in dark areas, increase the
gamma correction setting to compensate. Note: The range for this control has changed. After an upgrade from
version 1.2 or earlier to version 1.3 or later, the setting for Gamma Correction must be set again.
